  • Fore (Marconi) (Fore Systems (which new belongs to Marconi) ) : ForeRunner HE 155 and HE 622

    155 Mbit/s and 622 Mbit/s ATM adapter

    There are two line speed versions of the ForeRunnerHE ATM adapters - the ForeRunnerHE155and the ForeRunnerHE622.

    Fore Runner HE 155 and 622

    Utilizing 33/66 MHz PCI bus speeds and 64 bit data transfer options, ForeRunnerHE adapters ensure maximum performance allowed by standards. With silicon support for the ATM Forum ABR specification and up to 4,000 active virtual circuits (with any mix of CBR, VBR, UBR, and ABR) ForeRunnerHE adapters provide industry-leading functionality.

    Delivering 155 Mbps and 622 Mbps of full duplex bandwidth to connect servers directly to ATM backbones, the PCI-based ForeRunnerHE adapters are perfectly designed to manage the bandwidth demands of data, while still ensuring the quality of service (QoS) needed for voice and video.

    Servers with dual PCI buses can use multiple ForeRunnerHE 622 adapters on a single IP interface for 1.2 Gigabits of available bandwidth.
